A particular mail server I'm dealing with has rejected the sending of a plain text email with a few forward and backslashes in it. It's possible it's confusing these with something else.
The email is simply a contact form on a website, so it's a blurb of text written by someone.
What's the best method for escaping or doing otherwise to prevent issues like this?
I could just strip out all the slashes, but that seems a little crude.
